Overview
The HDPE Plain End Coupling is a robust mechanical pipe fitting designed to connect two plain-ended HDPE pipes securely and efficiently. By using precision-machined teeth and high-strength bolts, it creates a rigid and leak-proof connection without the need for fusion welding, making it ideal for projects where speed, reliability, and cost-efficiency are critical. This coupling ensures the joint maintains the pressure capacity of the HDPE pipe while simplifying installation in water supply, irrigation, and industrial piping systems.
The HDPE Plain End Coupling consists of:
Coupling body: Strong, corrosion-resistant material designed to withstand pressure and mechanical stress.
Teeth: Sharply machined to bite into the HDPE pipe outer surface.
Bolts & nuts: Four bolts evenly spaced to drive the teeth into the pipe for a secure hold.
Installation is straightforward: the coupling is positioned over the pipe ends, and bolts are tightened to drive the teeth into the HDPE surface. Once secured, the joint forms a mechanical seal that exceeds the pipe’s pressure rating, eliminating the need for expensive fusion tools.
